Ironically though, Gowalla's new data may likely appeal to advertisers more than ever before. Each interaction is now within a very defined context -- travel and tourism. There's no need to try to filter out locals vs. tourists with this. Companies will know exactly who is using Gowalla and why. These predefined areas will be a huge leg up in negotiations with companies. Actually, you're also off on travel being less profitable. In fact, global travel and tourism is one of the largest markets on the planet, with $919 Bil in expenditures last year[0]. It's also astoundingly broad -- nearly every country on the planet, big or small, poor or rich, has a significant tourism economy. This is the big cash cow that Gowalla's chasing.
